Alaska’s new climate threat: tsunamis

In Alaska and other high, cold places around the world, new research shows that mountains are collapsing as the permafrost that holds them together melts, threatening tsunamis if they fall into the sea.

Scientists are warning that populated areas and major tourist attractions are at risk.

In 2015, a landslide on a slope that had also crept for decades, created a tsunami that sheared off forests 193 meters up the slopes of Alaska’s Taan Fiord.

Tsunami set off by volcano sweeps Indonesia coast

A tsunami killed at least 168 people and injured hundreds on the Indonesian islands of Java and Sumatra following an underwater landslide caused by the eruption of Anak Krakatau, officials said on Sunday.

Anak Krakatau is the island that emerged from an area once occupied by Krakatau, which was completely destroyed in the 1883 disaster which killed more than 36,000 people in a series of tsunamis following an eruption of Krakatau. It first appeared in 1927 and has been growing ever since.

Coastal residents reported not seeing or feeling any warning signs, like receding water or an earthquake, before waves of up to two meters washed ashore, according to media.

Hundreds of homes and other buildings, including hotels were “heavily damaged” in the tsunami which struck along the rim of the Sunda Strait 21h27 on Saturday.

Authorities warned residents and tourists in coastal areas around the Sunda Strait to stay away from beaches and a high-tide warning remained in place through till Dec. 25.

With height of 30-90 cm, the event has produced 168 fatalities, 745 injured, 30 missing, 558 houses damaged, 9 hotel units damaged, 60 damaged food stalls, 350 boats damaged.

Marine Invaders

The devastating 2011 tsunami in Japan dragged several thousand tons of debris out to sea. Empty ships, splintered docks, wooden beams from homes, TV sets, refrigerators, buoys, buckets and plastic bottles crossed the Pacific Ocean in the months and years following the disaster.

The wreckage was a ghostly sight as it washed up on beaches from Hawaii to Alaska. But a new study claims the tsunami debris was actually teeming with life.

Scientists counted nearly 300 species from Japan that hitched rides across the ocean aboard debris.

Rare mega-tsunami in Greenland

On the evening of June 17, residents in the Greenland village of Nuugaatsiaq felt a low rumble shake the ground.

Within five minutes, a giant tsunami arrived, caused by a massive landslide in Greenland’s Karrat Fjord. The wave washed away 11 homes, leaving four people in the town of 84 residents presumed dead. But because the tsunami struck in a remote location, researchers didn’t know how exactly it had originated and how big it had been. That’s crucial information, since another landslide is likely to happen in coastal Greenland very soon—and even more enormous waves will be on the way around the world as climate change worsens.

Tsunamis caused by landslides in bays can rise to incredible heights, travel at devastating speeds, and cause massive destruction. The biggest one ever recorded occurred in 1958 in Lituya Bay in Alaska, reaching more than 500 meters in height—almost as tall as the Sears Tower in Chicago or Canton Tower in Guangzhou. A similar, albeit smaller, tsunami is thought to have destroyed Geneva in 563 CE.

5,000-Year-Long Earthquake-Tsunami Record

The discovery of sediment layers in a seaside cave represents the longest record of tsunamis in the Indian Ocean, and the clearest record of tsunamis anywhere in the world.

When the December 26, 2004 Indian Ocean earthquake occurred off the west coast of Sumatra, Indonesia, the 9.1 magnitude event — the third-largest tremor ever recorded on a seismograph — was so strong that it caused the entire planet to vibrate by as much as 0.4 inches. The quake triggered a series of devastating tsunamis that killed up to 280,000 people in fourteen countries, inundating some coastal communities with 100-foot-tall waves. The tsunamis are now regarded as being among the deadliest natural disasters in all of recorded history.

Motivated to better understand quake and tsunami dynamics, scientists Charles Rubin, Benjamin Horton, and their colleagues have been studying the seismic history of the region. Archaeologist Patrick Daly at the Earth Observatory of Singapore (EOS) suggested that they excavate a sea cave about 22 miles south of Banda Aceh, Sumatra.

Analysis of the find, published in the journal Nature Communications, provides a 5,000-year-long sedimentary snapshot of tsunamis in the region. The record shows that eleven tsunamis were generated between 7,900 and 2,900 years ago by earthquakes along the Sunda Megathrust, a 3,300-mile-long fault running from Myanmar to Sumatra along the floor of the Indian Ocean.

The investigation additionally determined that there were two tsunami-free millennia during the 5,000 years, and one century in which four tsunamis struck the coast. The scientists could see that smaller tsunamis tend to occur relatively close together, followed by long dormant periods. These, in turn, tend to be followed by very strong quakes and tsunamis, such as the one that struck in 2004.

According to the researchers, the 5,000-year record of tsunamis represents the first such discovery in a sea cave, the first record of tsunamis over this long of a period in the Indian Ocean, and the clearest record of tsunamis from anywhere in the world.

The stratigraphy of the sea cave in Sumatra excavated by scientists from the Earth Observatory of Singapore, Rutgers, and other institutions shows lighter bands of sand deposited by tsunamis over a period of 5,000 years and darker bands of organic material, largely consisting of bat guano.

Tsunami rumour in the Philippines

A Tsunami rumour in Quezon province in the Philippines has claimed life of an elderly woman who died after she had a heart attack on hearing the rumour.

Some 5,000 people also fled their homes after receiving text messages indicating a tsunami was coming from Batangas.

According to the Philippine Institute of Volcanology and Seismology (Phivolcs), it is impossible to have a tsunami alert at this time in any part of the country as there was no significant earthquake in the past 24 hours.

Tropical Storms

In the Eastern Pacific:

Tropical Storm Amanda is located approximately 455 mi (735 km) SSW of the southern tip of Mexico’s Baja California peninsula and is moving east near 7 mph (11 kph).

The storm’s maximum sustained winds have decreased to near 35 mph (55 kph).

Hurricane Amanda unexpectedly regained strength briefly Tuesday, before resuming a predicted weakening far off Mexico’s Pacific coast where it posed no threat to land. The hurricane’s maximum sustained winds were about 105 mph (165 kph) Tuesday afternoon, after rising to 120 mph (195 kph) Tuesday morning. Weakening should continue and Amanda is likely to become a tropical storm by Thursday.

Tsunami Debris

Three years after the Japan tsunami, suspected bits of debris arrive on Washington shores. The disaster’s aftermath is still being felt in ways large and small, far and wide. On a beach in southern Washington, approximately 4,500 miles across the Pacific Ocean, debris that may be from the tsunami is washing ashore. Experts have yet to confirm the debris, which includes small fishing boats, foam blocks, and water bottles are all a direct result of the tsunami. However, many of the water bottles and assorted items of trash appear to have originated in Japan.

There are portions of the beach that look like a dump truck just emptied a huge pile of trash. Washington state has been keeping track of the debris that is confirmed to be from the tsunami. Items include boats, portions of docks, and volleyballs have all washed ashore over the past three years. Alaska, California, and Oregon have also been monitoring their coasts.

The most recent series of debris began to arrive on beaches on Friday. Authorities are investigating to see if the boats and other items can be identified. They will also be checked for invasive species. In addition to the mass destruction and thousands of deaths, the earthquake that caused the tsunami altered the spin of the planet, according to reports.

A small tsunami triggered by the 7.1 quake has hit Japan’s eastern coast – where the crippled Fukushima nuclear plant is located

The 30cm (1ft) waves reached the region after the 7.1 magnitude tremor struck at a depth of 10km (six miles), about 320km off the coast.

A tsunami alert issued for several areas was later lifted.

Workers at the Fukushima power station had been told to leave waterfront areas for higher ground. But a Fukushima spokesman later said there was no damage or change in readings at radiation monitoring posts around the plant.

Japan’s Nuclear Disaster Contamination Skyrockets

Radiation levels have soared in the groundwater beneath Japan’s crippled Fukushima Daiichi nuclear power plant in the wake of torrential typhoon downpours and the forced release of radioactive water being stored around the plant.

Officials estimate that 400 tons of radioactive groundwater are now flowing into the Pacific each day. That’s in addition to any runoff of water from rain on the surface.

The level of radiation in a drainage ditch at the facility has also risen exponentially, according to the plant’s operator, the Tokyo Electric Power Co. (TEPCO).

Water contaminated with radioactive materials flowed into the ditch when Typhoon Wipha hit the area on Oct. 2.

TEPCO says much of the water evaporated, leading to the surge in the density of beta particle-emitting materials in the remaining water.

The nuclear complex suffered meltdowns and hydrogen explosions following a devastating earthquake and tsunami in March 2011.

TEPCO and Japan’s nuclear regulatory agency has been unable to keep the resulting nuclear disaster from cascading out of control in recent months.

Officials say they are now looking for help from abroad on how best to scrap the ruined reactors at Fukushima Daiichi.

“We will set up a website in both Japanese and English to notify interested parties at home and abroad of our calls for decommissioning ideas so that we can offer more useful and practical proposals to the government,” the official said.

The process of decommissioning the reactors is expected to take decades.

Reactor damage is clearly visible from the hydrogen explosions that occurred shortly after the March 2011 earthquake-tsunami disaster.

Global Warming’s New Natural Disaster: “Himalayan tsunamis”

This summer’s devastating “Himalayan tsunami” is a grim omen for the future of the millions of people living downstream from the majestic mountain range.

The June floods wiped out the Hindu pilgrimage town of Kedarnath and may have killed as many as 6,000 people.

According to preliminary studies, dozens of houses were smashed and hundreds of religious pilgrims were swept away when a lake above the eighth century Kedarnath Temple burst its natural dam of loosely packed glacial sediment, sending a sudden deluge of water down on the town.

Many now believe it was an accident waiting to happen — and similar accidents will happen again and again as the region gets warmer.

Rising temperatures due to global warming are fast creating thousands of glacial lakes across the region. The growing volume of meltwater is dangerously increasing the risk of sudden glacial lake outburst floods (GLOF), according to the Kathmandu-based International Center for Integrated Mountain Development (ICIMOD).

As the volume of water increases, so does the pressure on the dams of ice or glacial sediment, called moraine, which hold the lake in place on the side of the mountain. Once that pressure reaches the tipping point, heavy rainfall from a sudden cloudburst, a landslide, or an earthquake can breach the dam, sending a deadly torrent of ice, rock and water down on the people living below.

The results can be catastrophic.

In the weeks following the June 17 flood disaster, tens of thousands of residents, tourists and religious pilgrims were successfully evacuated. But officials still believe there are at least 5,748 people missing across the north Indian state of Uttarakhand.

Hurricane Cosme was located about 410 mi (660 km) SSW of Cabo San Lucas Mexico. Cosme has strengthened into a Hurricane and is moving away from land. The storm’s projected path will now steer the system away from Mexico, while fierce winds and extremely rough surf threaten shipping interests in the region. The storm’s maximum sustained winds early Tuesday were near 65 mph (100 kph).

Cosme has claimed the lives of two people in Mexico and injured 19.

Tourists stranded on Arctic Ice

Twenty people are stranded on an ice floe in the Canadian Arctic, with the 50km long slab of ice breaking away from an island and floating several kilometres out to sea. The group, which includes foreign tourists, were stranded when the chunk of ice separated from Baffin Island sometime between Monday night and early Tuesday.

They aren’t likely to be rescued until early Wednesday morning local time. The group includes local guides as well as Canadian and foreign tourists. They have a camp, shelter and supplies. 10 hunters who were also trapped managed to cross over onto land after the ice split and their end floated close to shore Tuesday afternoon. The floe the tourists are on remains afloat.

Tsunami hits US East Coast

A tsunami was observed on June 13, 2013 on the US East Coast, Bermuda and Puerto Rico, the National Oceanic and Atmospheric Administration (NOAA) has reported.

At Newport, Rhode Island the tsunami wave reached just under 25cm above sea level.

According to the NOAA, Gages in Kiptopeke, Virginia, and Atlantic City and New Jersey also recorded similar peaks.

At least two divers were injured in Barnegat Inlet in Ocean County, New Jersey. Minor tsunami damage was reported at the yacht club to the dock and two boats.

Scientists are still trying to determine the cause of Tsunami. A so called meteotsunami has been related to a strong storm that moved through the region and offshore that day. Some believe that the continental shelf landslide, a rare event, could also have caused the Tsunami.
